Using a regular amp as a slave

[ggunn]

All I want is the ability to power more cabs than just two with my head, just my one head. I live for it's pre-amp tone. I don't want any coloration, and no other amps' tones involved, that's why I want to use a slave. And trust me I'd buy a slave, if I had the time or money to find one. (Using a red knob Sunn Concert Lead, looking only to use a matching red knob Concert Slave). But since I can't I'd like to just know the next best way to do it with your average guitar amp.

I think that we've told you more than once all the different ways that there are to play through multiple amps.

If you have a series FX loop or your blend is pre-loop, however, you can't do it this way - plugging something from the FX send without running that same signal back into the FX return will effectively mute the signal coming out of the main amp's speakers.

On the only amp I've played around with that had a series FX loop, the lockout jack was on the return, not on the send.

It's really not that complicated.Reread my above post and look at the pic below.Done this way you are accessing each preamp and full power section of every amp in the chain.If there is one amp in the chain that has a particular sound you like, crank it up and bring the others in with a little less gain or whatever and shape the E.Q.'s to reinforce it.
BTW, you will have better luck using one hundred watter and one 412.If it is the visual effect of a wall of amps you are after, just roll the others up there and dont plug them in.No one will be the wiser and you will still be on speaking terms with the soundman and your band mates.

Cool, Shep. I always wondered about that. The pic is pretty clear.

I've run two cabs off one head - it was my standard gig rig. I think the days of throwing 2-300 watts off the stage are pretty much vanished with the new PA technology. It's so nice to have your hearing intact.

Your question has been answered a few times.

slave out or effect loop out or preamp out of the main head connected to the slave in, effect loop return or power amp input of the second head.

It's really that simple. The only problem you can run into is if the amps you are using don't have any of those ins and outs. Since you haven't told us what amps you are using, we can't get super-specific and tell you exactly what the ins and outs on those amps are called.

FX Out/Pre-Amp Out to Pre Amp In and do the reverse from the other amp. And I'm good then?

I don't understand why you guys keep trying to tell me there's other ways to do it. This is the way I want to do it.

No one wants to see you smoke yer amp. Go ahead and do it the way you want. It's gonna work or it ain't. Tell us what happens.

FXout/preamp out to the POWER AMP in/FX return (in) of the second amp. That's it, you don't have to do the reverse. The second amp just sits there and plays the signal coming from the first amp. All the controls on the first amp run the entire rig.

Tell us what amps you are using and I can tell you exactly what you need to do. The reason you are getting 12 slightly different answers is because all amps don't have the same ins and outs on them.

Example, that Marshall setup in the picture won't work if the amps you are using don't have the high and low input like those marshalls do. Tell us what amps you are using and the guessing stops.

If by "pre amp in" you mean the front panel input jack, then no, that will run your signal through the amp's preamp, which will color the sound. What you want is the FX return. Also, what do you mean, "do the reverse from the other amp? You shouldn't have to do anything, provided the FX send doesn't split the preamp signal.

And you've been given the right answer by damned near everyone who's posted here, I don't understand your frustration. You're either REALLY bad at explaining what you're trying to do, or...

Think of each guitar amp as having two different parts: The preamp and the power amp.

The preamp is where you are going to get your distortion and the tone.

The power amp is what brings the level of the preamp signal up to push the speakers at the volume you want.

What you are doing when you are slaving two amps together is:

1. plugging the guitar into the preamp of the first amp

2. splitting the signal after the preamp of the first amp

3. running that preamp signal into the power amp of both amps.

That is all you are trying to accomplish. Half the job is done for you because the preamp in the first amp is already connected to the power amp in the first amp. So all you have to do is tap into the preamp signal of the first amp (through a slave out/FXout/preamp out/line out) and connect it to the power amp of the second amp (through the slave in/FX return/power amp in)

Again, if you told us what amps you are using, we could tell you what the inputs and outputs are labeled on those specific amps.

Thank you. And I already told you guys, twice, SUNN CONCERT LEAD (red knob) and probably just a some tube Marshall piece or crap.

So, FX/Pre-Out (AMP 1) to FX-In (AMP 2) and I'm golden?

And Farview, thanks too.

The only reason this is all a jumble, is because I've tried being super specific then no one helps me because they have no experience with my 40 year old amps and tell me to go to a non-existent help center. (I.E. look at the maunal, etc. etc.)
